ABSTRACT:
A hydraulic stump cutting and earth digging apparatus including a balanced main supporting frame of a vehicle member and an adjustable telescopic channel frame cutter boom, the boom comprising a forward centrally disposed rotatable cutting wheel having a plurality of radially extending cutting teeth circumferentially mounted thereon. The channel frame cutter boom further includes a hydraulic motor contiguously mounted with the cutting wheel and having a common axis for rotation. A double pump and motor for circulation of hydraulic fluid to the hydraulic components of the apparatus is mounted on the main supporting frame thereby providing a telescopic cutter boom which is lighter in weight and more accessible to tighter places than conventional hydraulic stump cutters. In one embodied form the adjustable telescopic channel frame cutter boom is provided with flexible sideflaps which permits the removal of tree stumps situated close to permanent obstructions yet provides an effective means for controlling cut material through the channel frame of the boom.
